This example belonged to Air Chief Marshall Edmund Cuthbert Hudleston KCB, GCB, ADC who was born in Kalgoorlie, Western Australia. Rather than joining the RAAF he entered the Royal Air Force in 1927 and spent 3 years as a flying instructor at Cranwell. Later he was Group armament officer in support of operations on the North West Frontier and mentioned in despatches. In 1941 he was part of the Air Staff, HQ Middle Eastern Command. During the war he was one of the few senior officers permitted to read top secret signals (ULTRA) emanating from the breaking of the German Enigma system. He was seconded to the Turkish Air Force and in 1944 was promoted to Air Vice Marshall as head of 84 Group, 2nd Allied Tactical Air Force in Europe. After the war he was eventually made Vice Chief of the Air Staff. Hudleston died in December 1994. A lovely rare cap that displays very well. Stock code U22577.
